3 Claims. (01. 292-226) This invention relates to devices for use with window sash of the vertically sliding type to hold the latter in open position and also to lock the sash in either closed or open position, and the object of my invention is to devise a construction which is easy to install, simple and effective in operation and which is also simple tomanufacture.

I attain my object by constructing the device substantially as hereinafter described and illustrated in the accompanying drawing in which Fig. 1 is an elevation of part of a window frame and sash showing my holder applied thereto;

Fig. 2 an end view of the holder;

Fig. 3 a vertical section taken on the line 33 in Fig. 2, but with the locking device out of action;

Fig. 4 a plan view of the blank from which the locking member is formed.

In the drawing like numerals of reference in dicate corresponding parts in the different figures.

it indicates part of a window frame, ill the lower sash and it! the upper sash. At least the lower sash is arranged to slide vertically in the frame.

To hold the lower sash in any position to which it may be raised, I provide the holder which I will now describe. The holder comprises a base i, which is provided with a pair of spaced posts 2 which support a pivot pin 3. The base and posts are preferably formed, as will be seen from Fig. 2 by bending a flat piece of metal upon itself and then upwardly to form the posts. The base i is provided with holes for the passage of screws 4 for securing the base to the top of the lower sash as shown. Mounted on the pivot pin 3 is the downwardly inclined wedging member 5. The body of this wedging member, as will be seen from Figs. 2 and 3 comprises a piece of metal bent to substantially rectangular cross section, and in the open end adjacent the frame is inserted a nose portion 6 the end of which actually engages With the window frame and is suitably shaped for this purpose. The nose of :5 this wedging member may, however be made integral with the body by forming the whole as a single stamping.

As will be seen from the drawing, the wedging member is pivoted adjacent one end, its other 50 end normally tending to rock downwardly towards the sash, but is held in raised or wedging position by a spring I mounted on the pivot pin, one end of which spring engages the base I and the other end engages the underside of the top of 55 the wedging member.

In Fig. 1 the wedging member is shown in full lines in window supporting position, and in dotted lines in released position. The wedging member may be rocked to released position by engaging the Window with one hand and by engaging the 5 wedging member with the other hand. To facilitate the release when the sash is raised to a high position, I provide the depending handle 8, which is connected with the end of a pin 9, which pin is also preferably used for securing 10 the nose portion of the wedging member in place in the main part of the latter.

It will be noted that the screws 4 are positioned a short distance in front of the pivot of the wedging member and to counteract any tilt- 15 ing action, the base is provided with a long rear extension I.

The parts heretofore described are intended to hold a window in raised position, and a. further object of my invention is to provide means 20 for locking the sash in closed position, or to prevent a partially open window from being further opened from the outside. I therefore pivot on the pivot pin 3 the locking member it. This locking member is formed from an integral piece 25 of metal which is bent to form two spaced sides and one end. In Fig. 4 is shown the blank from which the locking member is formed, H being the sides provided with holes I 2 to receive the pivot pin 3, I3 the end, or frame engaging por- 30 tion, and M a bridge piece connecting the sides.

To hold the locking member in frame engaging position a spring I5 is provided which is mounted on the pivot pin 3. One end of this spring is engaged in holes H3 in the sides of the 35 looking member and its other end has pivotally connected therewith a trigger member 28. This trigger member comp-rises a supporting arm. 26 and an operating arm 20". In Fig. 1 the trigger member is shown in the position it assumes to 40 hold the locking member in locking position, while in Fig. 3 it is shown rocked to hold the locking member out of action. The end of the supporting arm of the trigger member, it will be noted, engages against the edges of the posts 2 when in supporting position. It will be noticed that the posts 2 are provided with notches 2! to receive the end of the operating arm of the trigger when it is desired to hold the locking arm out of action.

The sides of the locking member are preferably notched at 22 to receive the pin 9 and thus permit the frame engaging ends of the holding and locking members to move close together if necessary to ensure proper holding and locking action.

It will be seen from the above description that I have devised a simple device which may be used for holding a sash in raised position and also used to lock the sash in either closed or partially open position, and that when desired the locking mechanism may be thrown out of action, while permitting the holding mechanism to function.

What I claim as my invention is:-

1. In a sash holder, the combination of a base having a pair of spaced posts extending upwardly therefrom; a pivot pin supported by said posts; a downwardly inclined wedging member on said pivot pin; spring means normally tending to swing said wedging member upwardly; said wedging member comprising a hollow body portion and a frame-engaging nose-piece fitted in the end of said body portion; a pin extending through said body portion and nose piece to hold the latter in position; and a handle depending from one end of said pin by means of which the wedging member may be lowered against the action of the spring means.

2. In a sash holder, the combination of a support; an upwardly inclined wedging member pivoted on said support; a spring lever also pivoted intermediate its ends on said support, one end of said spring lever being engaged with said wedging member; and a movable support pivotally connected with the other end of said spring lever.

3. In a sash holder, the combination of a support; an upwardly inclined wedging member pivoted on said support; a spring lever also pivoted intermediate its ends on said support, one end of said spring being engaged with said wedging member; and a movable support pivotally connected intermediate its ends with the other end of said spring lever, said support when in one position being adapted to hold the attached end of the spring lever in raised position, the first mentioned support having shoulders with which the other end of the movable support engages when it is out of spring-lever supporting position.
